Description

A kind of temperature control forging press based on PLC
Technical field
This utility model relates to a kind of forging equipment, particularly to a kind of temperature control forging press based on PLC.
Background technology
Forging press is the common equipment of metal blank part processing.Forging Technology needs blank is heated to uniform temperature, profit Blank is made to produce plastic deformation and obtain certain profile and mechanical performance by the external force of hydraulic machinery.Temperature pair due to blank The mechanical performance of forging and stamping has considerable influence, is the key parameter of Forging Technology.Conventional swaging processes needs to rely on workman to observe blank Part surface color judges blank temperature and determines forge time, there is artificial decision factor, affects blank performance, even Forging equipment is damaged.
Summary of the invention
The purpose of this utility model is aiming at the deficiency that prior art exists, it is provided that a kind of temperature control based on PLC is forged and pressed Machine, utilizes temperature sensor to record the temperature of blank, judges temperature range by PLC and utilizes oil pump to supply as hydraulic cylinder Liquid, it is ensured that the temperature range of Forging Technology, is prevented effectively from artificial erroneous judgement, obtains more preferable metal forming machinery performance.
A kind of temperature control forging press based on PLC, is characterized in that: include hydraulic cylinder, pressure head, blank, temperature sensor, A/D converter, PLC, oil pump first, oil pump second and fuel tank, described hydraulic cylinder is fixed in frame, and hydraulic cylinder is provided with and fuel tank The top oil drain out of connection and bottom oil drain out, piston and hydraulic cylinder endoporus interference fits, piston rod is arranged on piston, pressure head Being arranged on bottom piston rod, described blank is placed on immediately below pressure head, and described temperature sensor is positioned at below blank, described temperature Sensor is connected with PLC by A/D converter, and described PLC connects oil pump first and oil pump second, described oil pump first and liquid respectively The top oil-in of cylinder pressure communicates, and described oil pump second communicates with the bottom oil-in of hydraulic cylinder.
The temperature of temperature sensor detection blank, the analogue signal of temperature sensor becomes numeral letter through A/D converter Number, PLC detect this temperature be positioned at threshold value within and start oil pump first, the top oil drain out of hydraulic cylinder is closed, bottom oil drain out Opening, hydraulic oil is injected hydraulic cylinder top by oil pump first, and hydraulic oil promotes piston downward, and piston rod forges and presses blank by pressure head; When PLC detects the digital signal of temperature sensor not in threshold value, PLC starts oil pump second, closes oil pump first, hydraulic cylinder Top oil drain out open, bottom oil drain out close, hydraulic oil is injected bottom hydraulic cylinder by oil pump second, hydraulic oil pass through piston band Move on dynamic piston rod.
Accompanying drawing explanation
Accompanying drawing 1 is overall structure schematic diagram of the present utility model.
In upper figure: hydraulic cylinder 1, piston 1.1, piston rod 1.2, pressure head 2, blank 3, temperature sensor 4, A/D conversion Device 5, PLC6, oil pump first 7, oil pump second 8, fuel tank 9.
Detailed description of the invention
In conjunction with accompanying drawing 1, this utility model is further described:
As it is shown in figure 1, this utility model includes hydraulic cylinder 1, pressure head 2, blank 3, temperature sensor 4, A/D converter 5, PLC6, oil pump first 7, oil pump second 8 and fuel tank 9, described hydraulic cylinder 1 is fixed in frame, and hydraulic cylinder 1 is provided with and oil The top oil drain out of case 9 connection and bottom oil drain out, piston 1.1 and hydraulic cylinder 1 endoporus interference fits, piston rod 1.2 is installed On piston 1.1, pressure head 2 is arranged on bottom piston rod 1.2, and described blank 3 is placed on immediately below pressure head 2, described temperature Sensor 4 is positioned at below blank 3, and described temperature sensor 4 is connected with PLC6 by A/D converter 5, described PLC6 Connecting oil pump first 7 and oil pump second 8 respectively, described oil pump first 7 communicates with the top oil-in of hydraulic cylinder 1, described oil pump second 8 Communicate with the bottom oil-in of hydraulic cylinder 1.
Temperature sensor 4 detects the temperature of blank 3, and the analogue signal of temperature sensor 4 becomes through A/D converter 5 Digital signal, PLC6 detect this temperature be positioned at threshold value within and start oil pump first 7, the top oil drain out of hydraulic cylinder 1 closes Closing, bottom oil drain out is opened, and hydraulic oil is injected hydraulic cylinder 1 top by oil pump first 7, and hydraulic oil promotes piston 1.1 downwards, lives Stopper rod 1.1 forges and presses blank 3 by pressure head 2;When PLC6 detects the digital signal of temperature sensor 4 not in threshold value, PLC6 starts oil pump second 8, closes oil pump first 7, and the top oil drain out of hydraulic cylinder 1 is opened, and bottom oil drain out is closed, oil pump second Hydraulic oil is injected bottom hydraulic cylinder 1 by 9, and hydraulic oil is driven by piston 1.1 and moves on piston rod 1.2.
The invention has the beneficial effects as follows: provide a kind of temperature control forging press based on PLC, utilize temperature sensor to record hair The temperature of blank, judges temperature range by PLC and utilizes oil pump as hydraulic cylinder feed flow, it is ensured that the temperature model of Forging Technology Enclose, be prevented effectively from artificial erroneous judgement, obtain more preferable metal forming machinery performance.
